I can get good meausurements from a machined Surface, but e.g. when I try to scan a coin, only features with a depth of 16 um are measured (with 10X objective). I see there are nice examples of a Euro cent. I wonder what type of settings one should use to get such mesaurements.

The scan that you see on the ProfilmOnline homepage was stitched together using a 10x objective with a digital zoom of 1x. The scan length was 280 µm with a backscan of 30 µm and used the envelope center analysis mode with an envelope threshold of 1,25%. This was done with the fast scan speed and covered an area of 23,5 x 23,5 mm.

I’ll get in contact with you via email in order to optimize your scan settings with the 10x objective.
